Abstract

Three sources of protein (A = soybean oil meal; B= cottonseed oil meal and C = fish and soybean oil meal) were tested in concentrate rations for calves. Thirty-six one-week oil calves (18 males and 18 females) were used in a randomized block design. The experiment lasted 84 days and during the first 42 days the animals received milk at a rate of 4 kg/animal/day, one of the concentrates and grass hay (Brachiana decumbens) ad libitum. During the last 42 days the animals received one of the concentrate mixtures limited to 2 kg/animal/ day and grass hay ad libitun. Although there were no significant differences between sex and between treatments, the performance of the animals fed fish and soybean oil meal were slightly superior liveweight gain and feed conversion) than the performance of the animals fed the other 2 sources of protein. The low quality of the hay fed (4,8% CP and 34,9% CF in dry basis) and the limitation of the concentrate intake to 2 kg/animal/day, probably affected the liveweight gain during the last 42 days of the experiment (0.444; 0.450 and 0.549kg/animal/day for sources of protein A, 13 and C, respectively).
